绿色理念在山区公路改扩建工程中的设计实践

山区公路改扩建工程地形地质复杂,征地拆迁困难,对生态环境影响较大。为了将绿色公路的设计理念贯穿在项目设计的各方面和全过程,首先系统研究了公路工程绿色发展理念;然后在总结山区公路改扩建工程特点的基础上,针对性地提出了基于绿色公路理念的山区公路改扩建工程设计要点和原则;最后以省道S478山区公路改扩建工程为例,从线位优化、指标选取、断面布设、景观规划等方面开展设计实践,最大限度降低对山区自然生态环境的影响,为绿色公路理念在山区公路改扩建工程中的设计实践提供参考。

Design Practice of Green Concept in Mountain Highway Reconstruction and Expansion Project

Aiming at the problems of complicated terrain and geology,and the difficult land acquisition and demolition,the mountain highway reconstruction and expansion projects will greatly impact the ecological environment.In order to make the design concept of green highway throughout all aspects and the whole process of the project design,the green development concept of highway engineering is systematically studied firstly.Then on the basis of summarizing the characteristics of mountain highway reconstruction and expansion project,the design essentials and principles especially for the mountain highway reconstruction and expansion projects based on the green highway concept are put forward.Finally taking a provincial highway of S478 Mountain Highway Reconstruction and Expansion project as an example,the design practice is carried out from the aspects of line optimization,index selection,section layout,landscape planning,etc.,which minimize the impact on the mountain natural ecological environment and provide the reference for the design practice of the green highway concept in the mountain highway reconstruction and expansion projects.
